Two: The Polo and TAC pants are not a "traditional" uniform.

The Polo and TAC pants are referred to in CAPR 39-1 as the "CAP Corporate Working Uniform".
Ref: CAPR 39-1 Para 5.3

So they are a uniform and there is a prescribed way to wear it.

But are they "Traditional"?

But are they "Traditional"? 

That depends entirely on your frame of reference, hence Nin's prior response. Personally, my idea of a "traditional" uniform is the Shade 1 khaki uniform from the 1960s. YMMV.

I cannot argue with that Sir!
